Saifu Ants win… Even the fucking honey badgers run when these guys move.
#1 on the above list-
"Siafu ants are also called driver ants, safari ants, and army ants. They live primarily in central and east Africa, both in jungle and on savanna. They have no eyes. They communicate and navigate by smelling pheromones, and every few years a colony of 50,000,000 will decide to pick up and move in search of more fruitful hunting grounds.
When they move, they form columns on the ground, with the smaller worker ants inside a tunnel formed by the larger soldier or guard ants. The ants average about an inch long, with the winged males the largest ant known at over 2 inches. They have venom and can sting with their abdomens, but it is insufficient to kill large animals. Instead, they rely on their bite. They have mandibles strong enough to cut through rhinoceros hide. And when the colony relocates, every animal in the entire area of many square miles, including the honey badger, leaves and may not return for weeks.
If one ant attacked you, you could stomp it or pick it off you. But ants don?t play fair. If you come within 25 meters of a colony on the move in column formation, they will smell you and come running to defend themselves. The bite is severely painful and once blood is drawn, your only defense is to run for your life. Attacking the ants is useless. A flamethrower might work but the ants do not know the use of fear and will either run across fiery ground to get at you, or wait until the fire dies away.
They do not run fast and are easy to avoid, provided you are able to get away. They are able to overpower any known animal, having brought down sick or injured elephants that could not escape. They have killed many people over the centuries, always infants or the injured, those who are unable to run. Once they are upon you, there is no easy way to get them off. Other ants will let go if you submerge in water. Siafu ants will hold their breath and bite for 3 minutes under water. A colony can strip an elephant to the bone in a month, and during that time nothing else except bacteria can approach the carcass. Vultures land on it and immediately fly away kicking ants off their feet.
They are used as natural stitches by the indigenous peoples. A single ant is picked up and allowed to bite on either side of a wound, and then the body is pinched off, leaving the head with jaws locked shut. They have venomous stings but hardly ever use them. They kill prey such as grasshoppers and small rodents simply by biting them to death. What they do is overwhelm any animal they can find and bite until the animal is incapacitated by agony. Smaller animals like insects are cut to pieces. The ants will enter the mouth of a larger animal and invade the lungs, biting the whole way, causing death by asphyxia."
